We introduce a second metric \(\omega \)  that is easy to compute in practice.
We make an additional assumption that the capture has a single look-at point in world space, which often holds true, particularly for captures involving a single centered subject.
Specifically, given a look-at point \(\mathbf {a}\)  by triangulating the optical-axes of all cameras (as per [1]}) and the frame rate \(N\) , the camera angular velocity \(\omega \)  is computed as a scaled expectation,
\(\omega =\mathop {\mathbb {E}}_{t,t+1 \in \mathcal {T}}\bigg [\arccos \Big (\frac{\langle \mathbf {a} - \mathbf {o}_t, \mathbf {a} - \mathbf {o}_{t+1}\rangle }{\Vert \mathbf {a} - \mathbf {o}_t\Vert  \cdot \Vert \mathbf {a} - \mathbf {o}_{t+1}\Vert }\Big )\bigg ]\cdot N.\)
